Description

Technical Field

[0001] The utility model relates to the technical field of wastewater recovery, in particular to a dilute sulfuric acid wastewater recovery and treatment device. Background Art

[0002] With the development of modern industry, sulfuric acid is widely used in chemical, steel and other industries. In many production processes, the utilization rate of sulfuric acid is very low, and a large amount of sulfuric acid is discharged along with acidic wastewater. If these wastewaters are discharged into the environment without treatment, they will not only acidify the water or soil, but also cause harm to the ecological environment.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN214060228U discloses a dilute sulfuric acid wastewater recovery and treatment equipment, including a first filter device, a first electric turbine, a first heating device, a second heating device, a condensing device and a finished product storage device. The first filter device is a cube with an internal space. An inlet pipe is arranged above the top plane of the first filter device, and an electric control valve is arranged on the inlet pipe. One end of the inlet pipe is connected to the first filter device, and the other end is connected to the electric control valve. The equipment also includes a second filter device, a second electric turbine and a distillation concentration device. Through the above method, the dilute sulfuric acid wastewater recovery and treatment equipment provided by the utility model is provided with an electric control valve at the water inlet, and the valve can be opened and closed according to the specific situation of the liquid level meter. The setting of the filter device is convenient for regular replacement. The first heating device is provided with a turbine driven by a motor, which can keep the water body in a flowing state, avoid the sediment generated by heating from adhering to the first heating component, and improve the service life of the equipment.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it was found that dilute sulfuric acid wastewater contains sulfuric acid, and direct discharge will cause pollution to the environment. When treating dilute sulfuric acid wastewater, a recovery and treatment device is used. When using the traditional recovery and treatment device, the dilute sulfuric acid wastewater is poured into a pool to mix with a solvent, which results in the need to manually pour the wastewater and the solvent, resulting in low subsequent efficiency and the inability to quickly mix the wastewater and the solvent. When removing impurities from the wastewater, the colloid precipitated in the device cannot be immediately removed, causing subsequent blockage in the device and a long subsequent manual cleaning time. The existence of these problems affects the use of the device. Utility Model Content
